I've had very good success with ETFs that are more focused on specific industries - clean energy, tech, EVs etc. I recently designed my own fund with a focus on E-Commerce, and to assign the weights I used the Quality/Value Rank from Stockopedia (essentially they combine a set of financial ratios for you, to determine how profitable a company is as well as how much the stock price has already 'priced in' future earnings).

The results almost feel like magic, but I am wary the market is being propelled heavily upward at the moment, and even a trump tweet has and can derail it. But as the saying goes, 'make hay while the sun is shining'.
